I have just finished enjoying reading Michael Fullan's little book --
I say 'little' on purpose because here is a book that is incredibly easy to read and very short -- just 70 pages - unlike other serious tomes on education that can be difficult to to make your way through even with the best of intentions.
I will write more about this book but the line that has captured my imagination is the one in the title. "The good leader is the one who knows the answer at the end of the lesson."
The skills that are required if that is the case are many and varied and not ones that are usually taught.
